Abstract

A vertical piston pump (1) for pumping waste material (3) containing a mixture of at least liquid and gaseous materials (3a,3b), the piston pump (1) including a vertical cylinder (5), a piston (7), pair of inlet and outlet ports (11a,11b), a gas release channel (15), a floating assembly (23) and a one-way gas relief assembly (29), the floating assembly (23) being cooperable with the first end (17) of the gas release channel (15) for allowing gaseous materials (3b) from waste material (3) being pumped in a lower pumping chamber (9) to evacuate into an upper release chamber (21), and the one-way gas relief assembly (29) coooperable with the second end (19) of the gas release channel (15) for allowing gaseous material (3b) originating from the lower pumping chamber (9) to be evacuated into the upper release chamber (21), and further configured for preventing gaseous material (3b) from the upper release chamber (21) from entering back into the lower chamber (9).
